Prince William and Prince George adorably sang along to Sweet Caroline at tonight's Platinum Party in the Palace gig.
The royals were front and centre of the royal box, and whilst Prince George seemed to be not as interested during the rest of the concert, when Sir Rod Stewart started singing the UK football anthem, he was soon singing along.
Sweet Caroline is regularly played to whip fans up at the UK's national football games and fans were thrilled to see William and George singing along to the iconic track - but Prince Charles didn't seem to know the words.
